Title: Easily dispersible pigment and production thereof
Inventor: IRIKOU KAZUO
IPC: C08K9/02
Filed: 1983-03-10
Abstract: PURPOSE:To obtain an easily dispersible pigment exhibiting excellent dispersibility when blended with a plastic, by treating a metal sulfate or acetate capable of forming a colloidal metal hydroxide with an alkali or alkaline earth metal silicate or silicic acid sol and carbon dioxide gas. CONSTITUTION:A metal sulfate or acetate capable of forming a colloidal metal hydroxide (optionally sulfuric or acetic acid being added to the sulfate or the acetate) and carbon dioxide gas are blown into a calcium hydroxide suspension until the carbonation rate reaches 3%. Further, carbon dioxide gas alone is blown into the suspension until the carbonation rate reaches 80%, and an alkali or alkaline earth metal silicate or silicic acid sol is then added. Further, carbon dioxide gas is blown thereinto and carbonation is terminated. The easy dispersibility of the resulting composite pigment when blended with a plastic such as rubber is considered to be due to the fact that, though the composite pigment is in the form of a primary particle having a particle size of 0.01mum, the pigment in the form of fine primary particle is dispersed as such in rubber due to non- cohesiveness of calcium silicate particles formed by the treatment with water- soluble silicic acid.

Filed: 1990-02-19
Abstract: PURPOSE:To add a load increase/decrease function to improve a printing accuracy by a method wherein bearing parts of a pressure roller are provided on a pressure spring of a sheet metal bent into a chevron shape, and a pressure roller shaft is supported by the bearing parts to be rotated. CONSTITUTION:When continuous paper 9a is used, a pressure spring 5 of a chevron-shape sheet metal is deflected because the pressure roller 4 abuts against the peripheral surface of a release shaft 6 other than the cutout part thereof, and the paper is not pressurized, but, for feeding the paper, a friction spring 7 applies a load to the paper 9a in addition to a load by a vinyl chloride sheet 8 to the paper 9a. When a cutform 9b is used, the pressure roller 4 pressurizes the paper by being abutted against the peripheral surface of the release shaft 6. At this time, the friction spring 7 is retracted so as not to abut on the paper 9b, and paper is fed. In this manner, a load can be adjusted for improving a line feed accuracy.

Abstract: PURPOSE:To relax the curvature precision of a lens surface and to easily obtain high optical performance by properly setting the center thickness of the lens or the position of the lens surface according to the curvature of the finished lens surface when the lens is manufactured by molding. CONSTITUTION:A toric lens 7 has high refracting power in its subscanning section so as to maintain optical conjugation relation between an optical deflector 5 and a photosensitive drum surface 8 and is formed in a meniscus shape having its convex surface on the image-plane side so as to correct image plane curvature accompanying a scan, and the curvature of the convex surface of the toric lens 7 is made large so as to have specific refracting power. The toric lens 7 is manufactured by plastic molding and as the curvature of the lens surface increases, it becomes difficult to machine the mold, etc., so that the curvature of the lens surface has an error. For the purpose, the lens center thickness, etc., is adjusted corresponding to variation in radius of curvature depending upon the manufacture state of the toric lens 7 in the meridian direction, thereby preventing the conjugation relation between the optical deflector 5 and photosensitive drum surface 8 from being lost.
